The rays shine on the surface of the bathtub for about five or six minutes, and the water in the entire bathtub turns clear turquoise.

Chen Ning took off his clothes, raised his feet and stepped into the bathtub, letting the water slowly submerge his body, then closed his eyes and slept a lot.

When he woke up the next day, the water in the tank had turned back to colorless and transparent, and if he felt it carefully, the α particles in his body seemed to be active, and the concentration had increased slightly.

There was no equipment to accurately test his physical condition, so he could only feel the changes in his body and the progress of the genetic optimization project as he continued to use his abilities.

So this house left traces of being burned by Chen Ning everywhere, and he never went to the kitchen to cook, and he could eat it directly with the fire palm in his left hand.

Every day when he sleeps, he soaks in the pre-prepared gene optimization catalyst solution, and wakes up during the day to make sure that the body is differentiating in the established direction, and he lives a very comfortable life.

On the 18th day of genetic optimization, after Chen Ning used the genetic optimization catalyst for three consecutive days without feeling any changes in his body, he determined that the genetic optimization project had been basically completed, and his strength had been unconsciously improved to level B.

After the gene optimization is completed, the body will have a long gradual transition period, after all, it takes time for gene translation and expression.

During this period, his physique will gradually evolve, absorb new element gases and transform α efficiency of particles, increase the concentration of α particles in his body, and α the power of particle transformation ability.

Chen Ning himself was not sure what level his strength would rise to after the gradual change period, but what he could be sure of was that the physique evolution brought about by genetic optimization would definitely greatly facilitate the development of his abilities in the future.

He packed two leather shoulder straps for the box where the genetic topometer parts were stored, and one night, without informing anyone, he slowly climbed down the outer ring of the earth building through the window on his back, and then left the high plate.

Perhaps it was the pressure brought about by the impact of the wanderers last time, the scanning density of the searchlight of the arrow tower was much greater than when he came back from the previous time, even if Chen Ning chose to go out of the city in the second half of the night, there were still people on the arrow tower who were dutifully vigilant and watching.

Patiently staying under the base of the wall until dawn, a group of sergeants went out of the city through a secret passage to change shifts, and he got the opportunity to activate the power plant immediately, and he successfully stayed away from the Tulou of the outer ring of the high plate.

Returning according to the map, Chen Ning was as fearful and cautious as when he came, never provoking any aliens, nor coming into contact with any scavengers or wanderers in the wild.

He was highly concentrated and couldn't sleep well, but he didn't feel the slightest tiredness, perhaps one of the benefits of genetic optimization engineering to transform his physical physique, he always felt full of energy and energy.

Ten days later, he arrived near Tongbei, but after a few thoughts, he still did not approach.

What he saw and heard in Gaopan gave him a lot of feelings, and also provided a lot of ideas for managing and building Qinghua, and he also wanted to go to Tongbei, which has a very different style, to take a look, but this will inevitably alarm his cheap ancestor, and the gene topology instrument he is carrying now will definitely be asked by him.

Last time, he saw that the unicorn arm was not greedy, maybe it had something to do with the fact that the thing focused on technology, but this time he directly carried a plug-and-play instrument, but he was not necessarily indifferent, Chen Ning couldn't afford to take the risk.

A few days later, he finally returned to Qinghua, which lasted two and a half months, and Qinghua was already more and more similar to what he had planned.

The layout of the arrow towers on the periphery of Qinghua's gathering place has not changed much, but the loaded weapons have all been upgraded, and it may be more appropriate to call them turrets now;

With Chen Ning's original production line for scavenger fighters and the more advanced production line he designed before leaving, the equipment of the soldiers in the gathering place has also been updated, and some elites even wear exoskeleton mechas;

There were iron ore, bauxite, and even oil and gas reservoirs near Qinghua, and Yunhe also stored a large number of enriched uranium bombs, which were the raw materials and power of Qinghua's industrial production.

In terms of culture, Qinghua has established a school in just a few months, and the knowledge and textbooks corresponding to the old world from primary school to high school have been compiled, and in addition, Chen Ning's group of old students have even built a TV station in their spare time!

After all, with the highly developed scientific and technological foundation before the end of the world and Chen Ning's advanced guidance, Qinghua has grown up rapidly, and the residents have been organized to engage in large-scale production, even if there is a passive opposition to interests, it is impossible to be as active as Gaopan, and it is often defeated as soon as it shows its signs.

Defeat is not only political, but also physical.

Because of this, the rumor that Chen Ning was in a dark dictatorship became loud, and even the memory of the Yunhe era began to have a market.

Of course, these statements are usually only circulated among the people who held management positions in the gathering place before Chen Ning's arrival, or among the high-level people in the so-called "company" in the gathering place, and the people at the bottom only knew that Chen Ning had a job when he came, could be fed, clothed and warm, and watched TV, and was grateful to him.

In general, Chen Ning is very satisfied with the development of Qinghua during his absence, and now there is only one problem left in the cluster, that is, the population is too small and the labor force is insufficient, which seriously drags down the production efficiency of the factories in the cluster and restricts the progress of many production projects.

Although there were waste pickers brought by Chen Ning last time as a supplement, the total number of people in that group was only a few thousand, which was a drop in the bucket.

The population within a radius of dozens of kilometers has been absorbed after review, and Chen Ning thinks it's time to take the initiative!

The violent forces in the settlements are now limited to a large number of troops, mostly temporary cameos, but still belong to the supervision teams led by the army system, which have taken on multiple tasks including maintaining law and order, patrolling and guarding the gathering places.

This is obviously unreasonable, the army should not have so many functions, there was nothing before, and Zhang Bei will not have so much spare time to take care of these things if he wants to fight in the future.

You can divide some people first, and set up a separate police station, security team, etc., just like Gaopan did.

These jobs must not be done by Chen Ning himself, just like he left these days to be a shopkeeper, a science and engineering student, I don't like to be good at and impatient to do these management and administrative things, and if you use the right person, you can do it better than yourself.

So Chen Ning called Zhang Bei and Uncle Fu, as well as Jiang Yihua, who was already in charge on his own, and the three of them were the actual managers of the gathering place.

He first proposed a plan to divide the army, and Zhang Bei was a little unhappy, perhaps thinking that this was a division of power for him.

But Chen Ning immediately put forward the army's preparation plan, and when Zhang Bei heard that he could fight, his face became very fast, and he was immediately overjoyed.

The preparation plan is divided into two aspects: on the one hand, after the internal functions are differentiated, some fighters who are still carrying out combat missions will strengthen military training, and on the other hand, some capable people will be sent to the field to reconnoiter and explore the existence of small human settlements in the surrounding areas.

It won't be too difficult to take them down, and Chen Ning plans to let the army try their hands and practice their troops first.

"Yes...... But I'm afraid that the ability of our gathering place is not strong enough to go through the field for dozens of kilometers to do reconnaissance......"

Chen Ning patted the square box he brought back and put on the table: "Call the barbarian king first, and then ...... There will be a way. ”
